It would be rather handy to use the 770 for presentations using a video projector. I've briefly googled and came across this
http://www.mobilityelectronics.com/h.../pitch-duo.htm

It's a box with bluetooth and video out, so one can broadcast their presentation via bluetooth to the box and control it with the nokia. Slightly expensive though at around 280 us dollars.

Anyone come across anything else along these lines ? Perhaps a USB device ?

Cheers
